System Control4.3 Register descriptionsThis section describes all the CP15 system control registers by coprocessor register numberorder. Table 4-2 on page 4-4 to Table 4-15 on page 4-13 provide cross references to individualregisters.4.3.1 Main ID RegisterThe MIDR characteristics are:PurposeProvides identification information for the processor, including animplementer code for the device and a part number.Usage constraints The MIDR is:• A read-only register.• Common to the Secure and Non-secure states.• Only accessible from PL1 or higher.ConfigurationsAvailable in all configurations.Attributes See the register summary in Table 4-2 on page 4-4.Figure 4-1 shows the MIDR bit assignments.31 24 23 20 19 16 15 4 3 0ImplementerVariantArchitecture Primary part number RevisionFigure 4-1 MIDR bit assignmentsTable 4-29 shows the MIDR bit assignments.Table 4-29 MIDR bit assignmentsBits Name Function[31:24] Implementer Indicates the implementer code:0x41 ARM Limited.[23:20] Variant Indicates the variant number of the processor.
